TO ALL WHOM .IT MAY CONGERN:

Be it known that we, JOHN A. BAHAM, ROBERT C. WILSON, and SAMUELFnENen,of Auburn, inthe county of Cayuga, and in the vState of New York,have invented certain new and useful Improvements in Machine forRemovingY the Wire Teeth from Cards; and do, hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeinghad to the accompanying drawings, and`to the letters of referencemarked thereon.

In the annexed drawings, making part of this speciiication' ,m

Arepresents a square frame, supported upon suitableA legs, and made inasubstantial manner. Lying crosswise of this frame, vand having hearingsin it, are the shafts T3, C, D, E, F, G, and H, the object of which vwill bedescrihed.

The shafts C and B are situated near one end of the machine, a little,distance apart, and are provided with drums, C' B', in the peripheriesof which are numerdus fine teeth. The object-of these toothed druins isto hold and feed up the cards from which the teeth are to be extractedto the device which extracts them. The card is passed over drum B andunder drum C'. V

Upon a. portion 4oi' the frame, which is elevated above the `mainportion, is secured a curved plate, zr. This plate x lies a sulicientdistance from the periphery of drum C' lto allow the card to passbetween them. After the card has passedV under drum C', it passesv upbetween said drum and the curveclplate' iv, and between two adjustableguides, y y, o n said plate. i i

The shaft D is provided with a loose pulley, m, a tight pulley, 1t, anua gear-wheel, S, at one end, and with a geur-wheel, I, at its other end,and at its centre with` a drum, composed of a sei-ies of toothed wheels,T'. The teeth of thesewheels'are very similar. to saw-teeth, but theirends, instead of being pointed, are square, as seen'in iig. 4. The card,aft-er passing over the plate as, passes over the toothed wheels T',presenting its back t0 them. i

The shaft E, which has its bearings in the` elevated portion oftheframe, is provided at one end witha gearwheel, R, which gears into wheelS4, and also with a series ot knives, E'. The card, after passing fromthe toothed wheels T', passes under the cutters or knives E', and, saidknives revolving with shaft E,elean,oilf the 4face of the leather of thecard, after the teeth areI removed.l

The shafts F, G, en d Hlio in thcsame vertical plane, shafts F and Gbeing providedjwith drums P and M, which are plain upon theirperiphcries, while shaft H is provided with a. drum, in the periphery ofwhich are nepointcd teeth. The leather of the cardfafter passing fromthe knives E',.pa ssesfover drum I), then between drumsl? and M,and'then between drums M and Q, oi 1 shaft H. Thc'sedrnms'hold theleather `tightly between, and sei-veto draw the card through themachin'e. i u l The shafts F, G, and H are revolved with suitablegearing, connected with that of shaft D, as follows:

The gear-wheel I of shaft D gearsA into a wheel, J, upon a short shaftat one side of the frame A. This short shaft, has upon it anothergear-wheel, K, which gears into a. wheel, L, on one end of shaft-G. Uponthe other end o'f shaft Gis a gear-wheel, G ',which gears into agear-wheel, H', on shaft H,`and into a gear-wheel, F', on shaft F,thuscounectingthc series-'of wheels together.

At one end of the machine, and beneath the shaft B, is a cross-bar, U,which has two arms projecting from it, marked W W', both of which haveholes through them, near their outer ends, through which a'rod, V,passes. One of the arms, W', is adjustable, having one end passingthrough a slot in the har U. The `card passes between the har 1U and rodV and arms W.W', the arm W being adjusted to the width of the eard. j n

In using this machine, the card is tirst passed between the rod V :rndbar U, then up-and over the toothed drum B',`its back beingpresented toor resting upon said drum., VIt then passes under drum C', with itstoothed orface side resting against said drum. Itthen passes up over theplate zr, between guides y y, then, over the toothed wheels T,presenting its back to them; then it passes under knives E', then overdruml, then between drums P and M, then between M and the toothed drumQ.

The toothed drum B partially loosens up the wires, and the toothedwheels T remove them by their teeth catehing into the loopsof the wireson thejbaek of` the card. The knives E' serve, as has been stated, toclean the face of the leather `after the wirehas been drawn out, whilethe drums P, M, and. Q serveto hold and draw the card through themachine. The plate .x is lprovidedwith slots, through which it issecured to the elevated frame, and, bymeans of these slots, can beadjusted to or' from the card, to regulate its pressure on tho wheels T.

'Having thus fully described our invention, we claim- 1. The toothed'drums B and C', the card-guide upon the bar U, and the adjustable platex, provided with the guides y y, oombined and arranged substantially asand for the purpose set forth.

2. The toothed wheel T', when used in combination with the drums BandC', as'and for thel purpose set forth. 3. The knives E and wheel T', incombination with the drums P, M, and Q, eonstrueted and operating as andfor thepurpose setforth. Y

In testimony that we claim the foregoing, 'We have hereunto set ourhands, this 3d day of February, 1868. JOHN A. BAHAM,
